Back to the wound healing process. After any soft tissue injury the body has specific series of responses, divided into 3 consecutive phases. The acute inflammatory phase. The proliferative or repair phase. And the tissue remodeling phase. The acute inflammatory phase occurs within minutes of an injury and continues over the next 3 days. If you stop this phase from going through completion by taking anti-inflammatories, your body doesn’t progress naturally into the proliferative and remodeling phases. Plus Professor James McCormack, from UBC, confirms there is no evidence that non-steroidal anti-inflammatories (NSAID) improve the outcome of acute sports injuries.
